Beczak / Beczak / Architekci Wraps a Multigenerational Konstancin House Around a Courtyard Among Pines

Konstancin-Jeziorna is one of the hardest places in Poland to build a large private house well. The old spa town south of Warsaw sits under conservation protection, its plots are thick with pine, and its streets carry a century of villas that set a high bar for restraint. BBB House by Beczak / Beczak / Architekci, completed in 2024 inside conservation zone A, takes on that brief at a scale of roughly 800 m² for a multigenerational family. That is a lot of house to place among trees without it reading as a lot of house.

What interests us is how the team, led by Magdalena Beczak, handles that bulk. They don't hide it behind fake modesty. They split the program into sculpted, vertically cut volumes, wrap them in sintered stone, and organise the plan as a semi-atrium that gives the street almost nothing and the forest almost everything. The facade's vertical fins are meant to echo the pine trunks around it. That analogy could easily be decorative. Here it does real work in giving the elevations depth.

A Closed Face to the Street

From the road, the house shows two stacked grey volumes, a glazed balustrade, a garage door and a sunken entrance tucked beside the ribbed cladding. The aerial view makes the strategy clear: a flat-roofed, solar-panelled footprint pressed into dense pine, with the bulk of the building turned inward. In a protected zone this is the diplomatic move. Neighbours and passers-by see a calm, opaque mass. They don't see a parade of glazing.

The entrance shows the same discipline. A timber door, a planter under glass and a drop in level are enough to mark arrival without a canopy or a porch. Because the approach is understated, the opening up on the garden side lands harder.

Fins as a Second Forest

The architects describe the vertical facade elements, with windows set back against them, as a reference to the pine trunks and to the spaces between trees. Read literally, that is a familiar metaphor. Read in low sun, it becomes something better. The fins catch shadows from real trunks and grasses, the tall windows reflect the pines back, and the elevation turns into a striped surface that changes through the day.

The rhythm is not uniform either. Along the long side facade, slim mullions alternate with deeper fins, and the corners are where the depth is most legible. The stepping stones across the lawn follow the same cadence and tie the ground plane to the vertical order of the walls.

Sintered Stone in Place of Plaster

The cladding is natural quartz sinter from Neolith, a sintered stone the architects chose for durability, weather resistance and near-zero maintenance. In the photographs it reads close to fine concrete. It is cool, grey and finely jointed, and it sits next to dark metal spandrels and glass parapets without fuss. For a house in a damp, shaded pine forest, where render streaks and timber greys unevenly, a surface that ages slowly is a practical choice as much as an aesthetic one.

The planting helps. Hydrangeas, grasses and gravel beds sit right against the base of the walls, so the stone never meets the ground as a hard plinth. That softness matters on a building this size.

The Semi-Atrium

The courtyard is the plan's real argument. Two wings fold around a lawn, linked by a glazed bridge, with a glazed library bay set between them. The atrium is left open on the side facing the wooded slope. So it is private without being sealed, and it borrows the forest as its fourth wall.

At dusk the logic reverses. Lit glazing and strip lights along the lawn edge turn the courtyard into a lantern seen from inside the plot, while the street side stays dark. For a multigenerational household, this shared outdoor room also works as social glue. Separate wings can look at one another across the grass.

Terraces Toward the Canopy

The site falls away toward the trees and a nearby river, and the house takes advantage with terraces on both levels and on the roof. A cantilevered upper terrace projects over the sloping lawn, a timber deck sits at ground level against a pale panel wall, and glass balustrades keep the views open toward the canopy.

Because the building is cut into the slope, the lower terraces feel close to the ground while the upper ones sit among the branches. You get two different relationships with the forest from one section, which is the right use of a falling site.

Light From Above, Concrete Within

Inside, the day zone is organised around a double-height space under a glazed roof, so daylight arrives from above and not only through the forest-filtered walls. A black steel stair and a full-height bookcase climb through the volume, and a timber stair lined with books runs up to a board-formed concrete wall raked by afternoon sun.

The material palette stays tight: raw concrete piers and walls, walnut-toned cabinetry, a dark kitchen island, art hung directly on the concrete. Floor-to-ceiling glass puts pine trunks right next to a red square painting. The interior does not compete with the setting. It frames it.

Plans and Drawings

The site plan shows an L-shaped footprint on a rectangular plot among scattered trees and neighbouring houses. The ground floor wraps garage, kitchen, dining and living spaces around the courtyard. Upstairs, bedrooms and bathrooms open off a gallery landing, and the master suite sits in its own volume. That separation suits a household of several generations sharing one address.

Why This Project Matters

Large houses in protected landscapes usually fail in one of two ways: they sprawl in glass and ignore the context, or they bury themselves in pastiche to satisfy conservators. BBB House avoids both. It accepts its size, breaks it into legible volumes, closes itself to the public realm, and gives its openness to the forest and the courtyard. That is a strategy other architects working in Konstancin and similar villa suburbs can borrow directly.

The pine-trunk fin is the kind of idea that can collapse into a slogan. What saves it here is follow-through: low-maintenance stone chosen for a damp forest climate, planting brought tight to the walls, terraces stacked to meet the canopy, and a roof that pulls light into the heart of the plan. Each decision supports the same aim of a house that coexists with the trees instead of clearing space for itself.
